Description
A 4S Battery Protecion System using the ABLIC S-8254 IC, this version auto activates the circuit using a relay when batteries are connected, this means power is output via P+ without having to apply a charge voltage. The quiescent current draw is about 160uA. The discharge cutoff voltage is 3.0V and the charge cutoff voltage is 4.2V.
